[HELP] Lenovo T520 High Sierra

4 posts in this topic

Recommended Posts

Hello,

I own a Lenovo Thinkpad T520 with this hardware:

CPU: Intel Core i5-2520M 2.50 GHz
Motherboard: Lenovo 4242Y13 Chipset Intel sandy bridge
RAM: 8Gb DDR3 dual channel
Graphics: Intel HD Graphics 3000
Storage: 320 Gb HDD 7200 rpm.
Wireless Card: Intel 82579LM Gbit network connection
Trackpad.
Ports:

  1.  - 2 USB 2.0
  2.  - 1 USB 3.0
  3.  - 1 VGA
  4.  - 1 Card reader
  5.  - 1 Ethernet

Is it Hackintosh compatible? I would like to install High Sierra, or at least El Capitan. I read that someone made it following the T410's guide, but they had the i7 version of the T520 with NVidia graphics. can you help me please?

Thank you for your time.

That model carries the same specs as many popular business Sandby Bridge laptops such as the Dell Latitude E6220 (or other E6x20 models) or HP EliteBook 2560p for instance: same CPU, iGPU, chipset, LAN card, etc. It's entirely compatible with all versions of OS X since good old Snow Leopard 10.6.8 up to latest High Sierra 10.13.4.

 

You only may encounter trouble with the wireless card because

1) Intel cards are not compatible with Apple's OS

2) ThinkPad are infamously subject to whitelisting, i.e. Lenovo BIOS only supports certain models.

 

According to p120 of the T520 Hardware Maintenance Manual, the only non-Intel WLAN card is a Realtek RTL8188CE model (FRU 60Y3247, would appear to be a Foxconn TH77H219). That's what your ought to run on as I believe it's compatible with OS X/macOS. Failing that, you'd need a modded BIOS where whitelist has been removed. Of course, a USB dongle remains an alternative to mini-PCIe card...

 

Thinkpad T410 was 1st gen Arrandale platform afaik, so quite different from your 2nd gen model.

      Hi, i can someone help me with installing mac OS Mojave on my HP ENVY - 15-as102na?
      I have an imac to use for setting up my usb & installing MacOS Mojave.There are various kext files etc that i'm not sure about and need some help as some are hardware specific.
      I tried previously but got stuck on an apple logo and couldn't get past that, and tried today and had problems with Clover.
      Once i get mac os on my 128gb m.2 ssd ( which i'll upgrade to either a 256gb or 512gb depending on how well this hackintosh works)
      I have a free 2.5" inch hdd bay where i'd like to install windows on in the future.
      I think i may have to replace my wireless card ( based on a few google results) which i'm fine with as long as i can see it working without just so i know i won't waste money
      Specs:
      Cpu: i5 7200u
      GPU: HD 620
      8GB ram
      Wifi card- Intel Wireless 7265 ( Intel® 802.11ac (2x2) )
      Motherboard - HP 81D2 & BIOS version is f.56

      Can someone help me fix reboot issue? Actually it reboots, but sometimes the hackintosh just hangs with screen off. Here is the Extra folder containing org.chameleon.boot.plist. https://drive.google.com/drive/folders/1MX8-DpQk9kaRUfjPcToxf-ElWh-bN6EY?usp=sharing  and the spec of the PC. https://drive.google.com/drive/folders/1NlcUNK5DBzJFxeFeuyt92eRjQqwO5T32?usp=sharing Can someone look at it? I might be doing something wrong. Any help will be greatly appreciated. Thank you.

      Hello Everyone ,,
       
      I'd  like to share with you my experience with Lenovo ThinkPad P50 ( EFI , and Installation Process with some tips ) Hopefully to be useful for anyone who own Lenovo ThinkPad P50 
       
      Before start I want to show you my device specs , and I'm  sure 99% this will work too with any P50 have different spec. specially Intel i7 CPUs:
       
      - Intel Xeon E-3 1535 v5 ( P530 Intel HD Graphics )
      - 32 GB RAM
      - 256 GB SK Hynix Nvme SSD pc401 hfs256gd9tng-62a0a - for Mac OS  ( be careful not all nvme ssd are compatible)
      - 256 GB Samsung Evo 850 SSD - for Windows 
      - 4K Screen 
      - Nvidia Quadro M2000M 4 GB ( Useless - Disabled )
      - Intel WiFi Card ( Should be change to a compatible Broadcom one )
       
      BIOS SETUP :
       
      I highly recommend this steps before going to BIOS SETUP according to my experience with this Laptop :
       
            *( Update your BIOS Firmware to the latest one using windows )
       
            *( Remove Battery , Open the back cover and unplug the small CMOS BATTERY for about  4~5 minutes and put everything back again )
       
             * ( Remove any SSD HDD Nvme disks , USB , DisplayPort , Dock .. etc during installation, keep only the target Disk )
       
      -------------------------------------------
      Now Power your PC and Press F1 to enter the BIOS SETUP
       
         - Reset BIOS to its defaults
         - Adjust Date and Time 
         - Config ----> Network ---> Wake Up on Lan ( AC Only )
                                                         Network Stack ( Disabled )
       
        - USB ----> USB UEFI support  ( Enabled)
       
        - Display ------> Total Graphic Memory (256 MB)
                                     Graphic Device ( Hybrid)
       
        - RAID -----> Disabled
       
        - Security -----> Security Chip Selection ( Discrete TPM )
                                     Secure BOOT ( Disabled )
                                     Intel SGX Control ( Software Control )
       
        - Start Up ------>BOOT Priority order ( USB HDD - Mac OS Disk - Windows - and so on ....... with this order )
                                     UEFI/Legacy ( UEFI Only )
                                     CSM Support  ( NO )
      ----------------------------------------------------------------------------------------------------------------------------------
       
      **   F1 to Enter Bios - F12 for Boot Menu
      ***   Delete the EFI Folder in your Installation USB and replace it with the Attached one 
      ****   Generate new serial for SMBIOS MacBook Pro 13.1
      *****    If your CPU is XEON then go to Config.plist CPU Section and Add 0x05A5 under Type ( Fix for Unknown CPU )
      ****** You can delete boot-args "brcmfx=1 & brcmfx-driver=#a" if you want , I used it in my case with 1820A card to fix wifi issue
      ******    After you successfully installed OS , now Copy the same EFI Folder to your main EFI Boot Disk Partition 
      *******    Now install all the attached KEXTS to "Library / Extensions"  using Hackintool.app or by any method and rebuild cache and repair permissions
      ********    Check and compare the KEXTS in Library/ Extensions and Delete the repeated ones from Clover / Kexts / Others ( Important don't duplicate the same kexts here and there )
       
      FYI : LiluFriend.kext include ( Lilu , WhatEverGreen, AppleALC , AirportBrcmFixup ) All In One 
       
       
       
      You are Done 
      ---------------------------------------------------------------------------------------------------------------------------------
       
      What is working :
       
      - 4K Intel HD P530 2048 MB 
      - AUDIO
      - CAMERA 
      - ALL USB 3 PORTS , NO THUNDERBOLTS 
      - Keyboard and TouchPad 
      - Battery indicator 
      - Display Brightness 
      - Sleep 
      - DSDT has been patched , USB Ports modified only to MacBookPro 13.1
       
                   See the Screen Shot 
       
      Important Notice For Future OS Updates Installations : 
       
      To avoid Kernel Panic during install any future updates process please remove ( FakeSMC.kext and LiluFriend.kext ) from Library/Extensions directory to Clover / Kexts / Others .
      After update process finish put them back to Library/Extensions and delete them from clover . I hope this is clear enough
      ---------------------------------------------------------------------------------------------------------------------------------
       
      Happy Hackintosh , Let me know if you have any issue or difficulties during installation or later , I will try to help you

      Hackintosh post

      Hi Everyone.  I really need some help.  My GPU just went out so, I'm replacing my Vega 64 with a 5700 XT and was planning on using my iGPU until the when/if the 5700XT is supported  in a mackintosh.   

      I've currently got a GB Z390 M Gaming with an 8700K.  16GB Ram. Running Mojave 10.14.2.  Right now everything is working perfectly (except I have to pull my Vega 64 to get the water block looked at - the pump was making weird noises this morning, but is still working at the moment as I use this sparingly).   
      The hack boots.   [Intel GPU shows up in system report](https://imgur.com/a/rwhDbSM) but the problem I'm facing is there is no output to it.  
      Does anyone know what I've got going wrong here?  I appreciate any help and will make a donation to a charity to celebrate when I get this figured out.  I've been working on this on and off all dang day.
